I show my kiddos a dot card, ten frame, a domino, etc. for about three seconds because I don't want my kids to count the dots. Then I ask them what did they saw. My kiddos come up with answers like "I saw 7 dots" "I saw 4 dots on the top and 3 dots on the bottom" "I know 4 and 3 is 7" "I saw a group of 4 and a group of 3." It's amazing how their number sense has improved tremendously.
Do you want to try it out? Here's a Subitizing freebie for you.
I just added a Subitizing pack. It has Subitizing cards for all year long.
You can grab it here.
This packet contains the following Subitizing cards:
Large ten frames

Have Fun Subitizing!
